Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, but this utility model is not limited to the following embodiments.

[0018] After automated injection molding production is completed, the surface quality of the produced products typically needs to be inspected. Post-injection surface inspection is a crucial step in quality control, directly identifying various appearance defects to ensure that the products meet appearance standards. These defects reflect underlying process problems, material issues, or abnormal mold conditions, providing real-time feedback for process optimization and mold maintenance.

[0019] Furthermore, timely detection of defects immediately after molding can effectively prevent defective products from flowing into subsequent high-cost processes, reducing rework and scrap costs. Therefore, visual inspection is an indispensable and important means of controlling quality, reducing costs, improving yield, and meeting requirements, even with the development of automated inspection.

[0020] However, in existing technologies, the surface quality of parts is usually inspected visually, which is inefficient and not conducive to automated production.

[0021] To address the aforementioned issues, this embodiment provides an injection molding receiving and inspection system for receiving products after the injection molding process and for inspecting the products. The injection molding receiving and inspection system includes a frame 11, a material tray 12 mounted on the frame 11, a driver for rotating the material tray 12, a receiving guide device mounted on the frame 11, and an inspection component 13 mounted between the receiving guide device and the material tray 12. The frame 11 is provided with a rotating shaft, and the material tray 12 is connected to the frame 11 through the rotating shaft. The material tray 12 is used to wind up the products after they have been inspected by the inspection component 13. The driver is used to drive the material tray 12 to rotate, providing power for winding up the products. The guiding device is used to adjust the direction and angle of the products entering the inspection component 13 to ensure that the inspection device can accurately inspect the products. The frame 11 is also equipped with a cleaning component 14, which is located between the guide device and the detection component 13. The cleaning component 14 is used to clean the product and prevent contaminants from interfering with the detection.

[0022] In this embodiment, as Figure 1 , Figure 2 As shown, product collection after injection molding refers to the process where the injection-molded products are attached to a strip of material, with several products evenly spaced on the strip, which is long and narrow. The injection molding collection detection system in this embodiment is used to detect the surface quality of each product on the strip. After detection, the strip is wound onto a spool 12. The power driving the strip to move towards the spool 12 and for the spool 12 to wind up comes from a driver that rotates the spool 12. The driver can be an electric motor, specifically a stepper motor. For ease of detection, the spool 12 does not rotate continuously but intermittently. When it stops, the strip remains stationary to complete the detection. After detection, the spool 12 rotates to move the next product to the detection assembly 13. The stepping distance of the spool 12 matches the spacing of the products on the strip.

[0023] The frame 11 can be a metal frame 47, and the guide device is used to adjust the direction of the conveyor belt. The cleaning component 14 is used to remove obstructions such as dust and adhering debris from the product surface on the conveyor belt to prevent interference with detection.

[0024] Furthermore, the detection component 13 includes a detection bracket and a CCD camera 21 mounted on the detection bracket. The CCD camera 21 is used to acquire images of the product surface. The injection molding receiving detection system can detect visible defects on the product surface based on the images acquired by the CCD camera 21.

[0025] In this embodiment, as Figure 2 As shown, the CCD camera 21 is a camera that uses a CCD sensor as its light-sensing element. It has wide and important applications in the field of industrial image inspection, mainly due to its unique performance characteristics that well meet the stringent requirements of industrial inspection.

[0026] Furthermore, the detection bracket includes a product guiding platform and a camera mounting platform. The CCD camera 21 is mounted on the camera mounting platform, and the product passes through the product guiding platform and its surface image is acquired on the product guiding platform. A spatial rectangular coordinate system is established in the space where the testing bracket is located. The spatial rectangular coordinate system includes mutually perpendicular X-axis, Y-axis, and Z-axis; the direction of product movement is parallel to the X-axis. The camera mounting platform is equipped with a Z-axis adjustment mechanism, which is used to adjust the position of the CCD camera 21 in the Z-axis direction, thereby adjusting the focus of the CCD camera 21 to the product surface to adapt to products of different heights. The Z-axis adjustment mechanism includes a Z-axis track 31, a Z-axis slider 32 mounted on the Z-axis track 31, and a Z-axis locking device 33. The length direction of the Z-axis track 31 is parallel to the Z-axis. The Z-axis slider 32 is connected to the CCD camera 21. The Z-axis slider 32 can translate along the length direction of the Z-axis track 31. The Z-axis locking device 33 can fix the relative position of the Z-axis slider 32 and the Z-axis track 31.

[0027] In this embodiment, the product guiding platform includes a base plate 22 and two side plates 23 disposed on the base plate 22. The base plate 22 and the two side plates 23 form a semi-enclosed structure. The material strip passes through the semi-enclosed structure. The distance between the two side plates 23 matches the width of the material strip. Accurate positioning of the material strip ensures that the CCD camera 21 can acquire a complete product image.

[0028] The product moves in a direction parallel to the X-axis on the product guide platform. The Z-axis is the height of the CCD camera 21. The Z-axis adjustment mechanism is mainly used for focusing the CCD camera 21. After the material strip is changed, the thickness of the material strip or the thickness of the product changes, and the height of the CCD camera 21 needs to be adjusted.

[0029] In this embodiment, the Z-axis locking device 33 is a screw. The Z-axis slider 32 has a matching threaded hole. The screw and the threaded hole are engaged by a thread. Rotating the screw allows it to pass through the Z-axis slider 32 and press against the Z-axis track 31, increasing the friction between the Z-axis track 31 and the screw, thereby fixing the relative position of the Z-axis slider 32 and the Z-axis track 31. Conversely, when it is necessary to adjust the position of the Z-axis slider 32, the screw is first loosened to separate it from the Z-axis track 31. At this time, the Z-axis slider 32 and the Z-axis track 31 can move relative to each other.

[0030] Furthermore, the camera mounting platform is also provided with a Y-axis adjustment mechanism, which is used to adjust the position of the CCD camera 21 in the Y-axis direction, thereby adjusting the shooting range of the CCD camera 21 to cover the area of ​​the product, so as to adapt to products of different widths. The Y-axis adjustment mechanism includes a Y-axis track 34, a Y-axis slider 35 disposed on the Y-axis track 34, and a Y-axis locking device 36. The length direction of the Y-axis track 34 is parallel to the Y-axis. The Y-axis slider 35 is connected to the Z-axis track 31. The Y-axis slider 35 can translate along the length direction of the Y-axis track 34. The Y-axis locking device 36 can fix the relative position of the Y-axis slider 35 and the Y-axis track 34. The Y-axis track 34 is connected to the camera mounting platform.

[0031] In this embodiment, the structure of the Y-axis track 34, Y-axis slider 35, and Y-axis locking device 36 is similar to that of the Z-axis track 31, Z-axis slider 32, and Z-axis locking device 33, except that the length direction of the Y-axis slider 35 is parallel to the Y-axis.

[0032] The Y-axis adjustment mechanism is used to adjust the position of the image captured by the CCD camera 21 to ensure that the range of the image captured by the CCD camera 21 can cover the product to be inspected.

[0033] Furthermore, the receiving guide device includes a material strip upper limit position 41 and a material strip lower limit position 42 disposed on the frame 11. The material strip upper limit position 41 and the material strip lower limit position 42 respectively include a roller in contact with the material strip, a connecting roller and a connecting arm of the frame 11; the material strip is a strip formed by connecting several products in sequence. The upper limit stop 41 and the lower limit stop 42 of the material belt contact two opposite sides of the material belt to adjust the direction of product conveying.

[0034] In this embodiment, the direction in which the material strip enters the injection molding take-up detection system may not match the product guide platform; specifically, this could be a mismatch in angle or height. The upper limit stop 41 and the lower limit stop 42 of the material strip respectively contact two opposite sides of the material strip to adjust the direction of product conveying.

[0035] Furthermore, the cleaning component 14 includes an air nozzle 43 and an air pipe connected to the air nozzle 43. The air nozzle 43 blows air toward the product surface to clean obstructions from the product surface.

[0036] In this embodiment, as Figure 3 , Figure 4 As shown, one end of the air blowing pipe is connected to the air nozzle 43, and the other end is connected to an external air source, which can be a blower or an air compressor. The air outlet of the air nozzle 43 can be flat.

[0037] Furthermore, the cleaning component 14 also includes a cleaning brush 44 and a cleaning driver 45 that drives the cleaning brush 44 to rotate. The cleaning brush 44 is capable of contacting the product surface and removing obstructions from the product surface by friction.

[0038] In this embodiment, the cleaning brush 44 may be cylindrical, with bristles or a sponge-like device on its outer surface to increase friction. The cleaning driver 45 may be an electric motor, connected to the cleaning brush 44 to drive the cleaning brush 44 to rotate.

[0039] Furthermore, the cleaning component 14 also includes an air intake duct 46, which is used to create a negative pressure space in the vicinity of the cleaning component 14 to keep the vicinity of the cleaning component 14 clean.

[0040] The suction duct 46 can be connected to an external suction pump. The suction duct 46 creates a negative pressure space in the area near the cleaning component 14 to maintain cleanliness.

[0041] Furthermore, the cleaning component 14 also includes a frame body 47, which includes a bottom connecting part and a top connecting part that are hinged to each other. The bottom connecting part and the top connecting part are respectively provided with an air nozzle 43, an air pipe, a cleaning brush 44, and a cleaning driver 45; the product surface is cleaned from both sides of the product.

[0042] The air nozzle 43, cleaning brush 44, and cleaning driver 45 are mounted on the frame body 47. The bottom connecting part and the top connecting part are hinged by a hinge or other means, and can be opened and closed. When changing the material belt, the bottom connecting part and the top connecting part are opened, the material belt is placed between the bottom connecting part and the top connecting part, and then the bottom connecting part and the top connecting part are closed.

[0043] Furthermore, a display screen 48 is also provided on the frame 11, which is used to display images acquired by the CCD camera 21.

[0044] The display screen 48 is connected to the CCD camera 21 and is used to display images captured by the CCD camera 21.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
